Abstract (en)
Provided is a method for preparing biomass graphene by using cellulose as a raw material. The method comprises: preparing a catalyst solution; carrying out ionic coordination and high-temperature deoxidization on cellulose and a catalyst, so as to obtain a precursor; carrying out thermal treatment and pre-carbonization; and carrying out acid treatment and drying to obtain the graphene. The method is simple, low in cost, high in production, high in production safety, and controllable in product dimensions and other physical properties. The graphene is uniform in morphology, has a single-layer or multi-layer two-dimensional layered structure; the dimension is 0.5 µm to 2 µm; and the electric conductivity of 25000 S/m to 45000 S/m. The graphene can be applied to electrode materials of super capacitors and lithium ion batteries, and can also be added to resin and rubber as an additive so as to improve physical properties of the resin and the rubber.
